l' Application led October 25, ISGL SerialNo. 229,925. f f l through an apparatus embodying the invengineer'; citizen' of Gerninny, residing at Mul nich, Bavaria, Germany. have invented cer- Q tom new and useful improvements in Gzis- I Puriiiers; and l do hereby declare the follo.-. ing tohe a full, clear, and exact description of theinvention, such as will enable others skilled in the nrt to 'which it .appertains to' make and use the same.' l

This invention relates `to apparatus foi-"the treatment liquidsand gases forevaporating, cooling,- heating', absorbing, purifying and thelikeobjects. `f

Forms of apparatus for this purpose haveV heretofore been \use(l consisting essentially` of a drum provided with longitudinally ex'- tendingribsand' a casing surrounding said drum and ribs, the gas passingthrougli the space betwee'n-thedrum and casing fron'rone end. to' the 'other and thev liquid passing through said space in the 'op osite genera direct-ion. In practice, the ri s have been given a more or lessinelined direction upon" the outer walls of tl'iedruin so'as to 'cause a spiral travel of tlieliquid in contactl with and under the inlluence of the Uns' pressure supe pleniented by its centrifugal ressue. i In the forms of apparatus iitherto known, .it hasnot been possible to regulate the capacity for treatment of the a paratus or the velocity or quantity of the nids' assingtherethrough, except by taking zitieA upmraitus ievinelination of theri s or 'to insert another drum having ribshrra'nged 'withgreater pr less obliqu'ity.

The object'of'this inventionl is to provide nn apparatus of this general character which is subject to regulation with'facility z ind without expense, this object being,r attained by providing the inner face of the easing sur- 'rounding` the drum with inclined channels or passages which, under the influence of the as pressure u onthe li uid, will cause the iquid to trave in a spira path-of greater i' less inclination independent of the inclination of the ribs upon the drum.

With this object in view, the invention resides in the structural features' hereinafter more elaborately described and particularly set forth in theclainis.

For purposes of illustration, a preferred embodiment of the invention with certain modifications is set out vin the accompanying Y drawings, in which:

gtiidin'gsuria'ces upon the` inner side of the casing; Figs. 3, 4 andiarefraginents s h'outhe 'construction of the guidingl channels; 6 shows the arrangement o f one formof guiding channels on the inner Wall of tli'ecasing; and Fig. 7 is a transverse section through A Y 'b indicates the ribsor'iianges extending the druin and ensinfr showingthe relation of Fig. 2 representsdilferent forms of longitudinally ot :ind upon the outer Wall of the drum b' mounted to rotate .Within the casing a upon-the shaft c. Into the space between the drum and casing, gas is introduced' at d nndlinds its exit at e, while Water o r other suitable liquid is introduced into the same space at a point not shown near the gas exit and finds its outlet from the opposite end at The ribs b may be 'arranged either par- :il el to the axis of the drum or they may be airinged at a slight inclination thereto.

The spiral channels arranged upon the inner n'sll of the easing may be formed in any suitable minimi-,but in order-to facilitate the removal of guidi-ng chonnels with a eertnin inclinntionA ond' .their substitution by channels having n. dii'llerent inclination, 4in` ord-er to regulate the operation of the appie rotos, :t removable guiding surface is provided. Y

ln Figs. 3,' 4 and' 5 are' shown one form of arrangement consisting' o'f :i wire netting composed of rods g extending substnntially parallel to ent-.h other and cross wires h inter. sectingl the rods g und interwoven therewith to forni a nett-ing. 'lhe rods g und wires h may be. of the saine size, but preferably they are of different sizes as shown. They may occupy a position very nearly nt right ongles to esch other as shown in Fig. 3, in which esse, the channels upon the. inner wall of the cas'rfr a' are inclined but slightly. and the treire of the liquid through the apparatus 'will oe slow, or therods g und the wires h .Figure 1 is a vertical longitudinal section l inglj.v rapid from the water inlet to the outlet.

The inner surface of the casing,

i formed es hereinbefore described, may be readily inserted .and removed, thus render# ino` 1tpmcticable to have several interchangeable linings and possible, by the mere ect of substitution, to regulate the operation of the apparatus with great nicety. The re ulatlon may be further effected by a mere s ifting or displacing ofthe parallel rods g within the casing so as to increase or diminish their inclination. Not only ma the guiding channels a formed between t e rods g be arranged at greater or less inclination, but the depth may also be Inode to vary by the use of rods g of different sizes, or if the channels are formed in the well of'the casing itself,

they may be mode of greater or less depth so that the water 1n passing through the space between the drum and casing will not only travel in a s iral direction through the chan# nels, but will also flow over the ridges separating the same end thus be given a. rilding effect. .This ellect is also produced by the cro wires over which the Water must flow vrhen traveling in the channels.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In s n apparatus of the character described, the combination with a rote drum provided with exterior longitudinal ri s, of o casing surrounding seid drum end provided upon its inner surface with ridges forming helicsl channels.

2. In en apparatus of the character described, the combination, with e. rote drum provided ndth exterior longitudinel ri s, of a easing surrounding seid drum and rovided upon its inner suriece with adjusts4 forming helical channels.

'3. In en apparatus of the character de scribed, the combination, with a rote drum provided with exterior longitudinal ri s, of o e ridges casing surrounding'seid drum and provided u on its mner fece with ridges forming helical c snnels and with cross ridges of lrss height.

4. In en apparatus of the character described, the combination, with e. rote drum provided with exterior longitudinal ri s, of a casing surrounding said drum, and a Wire netting arrangld upon the inner lsurface of the casing Wit its VWires extending in s. helical direction.

5. In an apparatus of the; character described, the combination, With e. rote drum provided with exterior longitudinal ri s, of a.
